我试图用一个HTML的机器人来创建一个sqlite的表，但它不能正常工作

I tried to use a HTML in android to create a table in sqlite but it is not working

样本HTML是这里

<!DOCTYPE html>
<html>
<head>
<title>Contact Example</title>

<script type="text/javascript" charset="utf-8" src="phonegap-1.0.0.js"></script>
<script type="text/javascript" charset="utf-8">

// Wait for PhoneGap to load
//
//document.addEventListener("deviceready", onDeviceReady, false);

// PhoneGap is ready
//
function onDeviceReady() {
    var db = openDatabase("Database", "1.0", "PhoneGap Demo", 200000);
    db.transaction(populateDB, errorCB, successCB);
}

// Populate the database 
//
function populateDB(tx) {
     tx.executeSql('DROP TABLE IF EXISTS DEMO');
     tx.executeSql('CREATE TABLE IF NOT EXISTS DEMO (id unique, data)');
     tx.executeSql('INSERT INTO DEMO (id, data) VALUES (1, "First row")');
     tx.executeSql('INSERT INTO DEMO (id, data) VALUES (2, "Second row")');
}

// Transaction error callback
//
function errorCB(tx, err) {
    alert("Error processing SQL: "+err);
}

// Transaction success callback
//
function successCB() {
    alert("success!");
}

</script>
</head>
<body onload="onDeviceReady()">
<h1>Example</h1>
<p>Database</p>
</body>
</html>

的Android 2.2 我无法看到任何数据库中创建的机器人。请一些建议
